How can I perform uploading files to the webserver without refreshing whole page?
AJAX UpdatePanel and standard FileUpload do not work together...
|

|
|
you can read this article : http://www.codeproject.com/useritems/simpleajaxupload.asp

I didn't mean that. The question was how to organize asynchronous upload of the file.

|
|
|
|
Have you got any similar information that doesn't need knowledge of PHP?

Hi,
I am Retrieving the binary image from sql database on web page. For that I have written following code in vb.net
Dim stream As MemoryStream = New MemoryStream()
Dim image As Byte()
Dim bitmap As Bitmap
Dim username As String
username = Session("memberuser")
con = New SqlConnection("server=ABC-0A55D6C3C90;database=satphere;uid=sa;pwd=")
Try
con.Open()
cmd = New SqlCommand("select photo from ViewProfile where userid = @userid", con)
cmd.Parameters.AddWithValue("@userid", username)
>>>>>>>>> image = CByte(cmd.ExecuteScalar())
stream.Write(image, 0, image.Length)
bitmap = New Bitmap(stream)
Response.ContentType = "image/gif"
'bitmap.Save(Response.OutputStream, ImageFormat.Gif)
bitmap.Save(Server.MapPath("TempImage/aa.gif"))
Image1.ImageUrl = "TempImage/aa.gif"
Catch ex As Exception
con.Close()
Stream.Close()
End Try
I am getting the error as
Value of type 'Byte' cannot be converted to '1-dimensional array of Byte'
line is mentioned by >>>>>>
C#.net code for same is working fine--------------as follwos
MemoryStream stream = new MemoryStream ();
SqlConnection connection = new SqlConnection(@"server=ABC-0A55D6C3C90;database=Test;uid=sa;pwd=");
try
{
connection.Open ();
SqlCommand command = new SqlCommand("select Picture from Image", connection);
byte[] image = (byte[])command.ExecuteScalar();
stream.Write(image, 0, image.Length);
Bitmap bitmap = new Bitmap(stream);
Response.ContentType = "image/gif";
bitmap.Save(Response.OutputStream, ImageFormat.Gif);
//bitmap.Save(Server.MapPath("TempImage/aa.gif"));
}
finally
{
connection.Close ();
stream.Close ();
}
can any one give me solution for this
Thanks to all

try this code
image = CType(cmd.ExecuteScalar(),Byte())

My knowledge of VB is rubbish, but I would say the problem is as follows:
cmd.ExecuteScalar() returns object, which is supposed to be array of bytes,
but your call CByte(cmd.ExecuteScalar()) is trying to convert this object into object of type byte (not array of bytes) and that causes your error.
Unfortunately, I don't know correct syntax in VB for casting object into array, I hope you do (otherwise you have to google it  )

ASP.NET Ajax doesn't support in .NET 1.1.
So, you have to choose other Ajax frameworks.. there are a lot of free ajax framework for ASP.NET 1.1. Check-out the link below if you interest..
Ajax Frameworks and Others.
If you are good at Javascript, you can probably use Prototype Javascript Library.

details view control or data grid control ? From where does your filter criteria come from.
|
|
|
|
|
In the insertitemtemplate in the details view.
in the dropdownlist I can show the items all I need is to filter these items to a 3 char input from the user.

Your client disable Javascript on his/her browser?
It is not possible to change the client's setting from web application. It is for security reason. So, what all you can do is that check whether the Javascript is enabled or disabled for the user's browsers. If it is disabled, you should check the validation from code-behind.
Since Ajax web application are so popular day by day, I don't care about those users who are disable the Javascript in my project. But Yes, the requirement may be varied from project to project....

You can not. That would mean intruding into user's personal browser preferences. I would say, you can have a disclaimer or an instruction to the user about required support for JavaScript in the web browser for your application to perform normally without insanity.
